Waking Up Late

I've woken up past 1 pm for the past... week. Although most people don't think it's healthy, it's been the natural time for me. Why? Because someone, in the middle of my REM cycles, wakes me up. A phonecall from my mother, my brother, my dad, all asking me for a favor while I'm groggy, only lightly irritated, and just desperate to finish the sleep cycle that has to start all over again. People LEAVE ME ALONE SO I CAN SLEEP AND WAKE UP BEFORE NOON.
